You can buy a 1 meter-long blood transfusion latex tube and a large catheter (there is no catheter, if there is a connection between them) in a drugstore, put about 500 ml of stirred light salt water or light soapy water or light coffee with a little temperature into the container, fill the hose with the liquid in front, then apply some lubricating oil on the top of the hose, gently insert it into the anus, and then insert the other end of the hose into the water of the container and hold it high. The liquid will spontaneously due to pressure. Cool and comfortable. When you feel bloated, pinch the anus and gently pull out the hose to prevent the body from flowing out. Hold it for 2 minutes, and then you can untie it. At this time, you will feel very comfortable and relaxed. It is recommended to order disposable intestinal cleaning bags twice a week. Or, just put the liquid in the bag, hang it high and insert the end into the anus, which is very convenient. It is a good habit to insist on washing intestines at home abroad. It mainly cleans the fecal attachments on the rectal wall, which greatly reduces the incidence of rectal cancer and prevents the rectal wall from absorbing fecal wastewater. You must stick to good habits. I don't know anything, I can communicate.
